Background
Function：Cysteine protease that plays a key role in autophagy by mediating both proteolytic activation and delipidation of ATG8 family proteins (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:21177865, PubMed:22302004, PubMed:26378241, PubMed:27527864, PubMed:28633005, PubMed:28821708, PubMed:29232556, PubMed:30076329, PubMed:30443548, PubMed:30661429). Required for canonical autophagy (macroautophagy), non-canonical autophagy as well as for mitophagy (PubMed:33773106, PubMed:33909989). The protease activity is required for proteolytic activation of ATG8 family proteins: cleaves the C-terminal amino acid of ATG8 proteins MAP1LC3A, MAP1LC3B, MAP1LC3C, GABARAPL1, GABARAPL2 and GABARAP, to reveal a C-terminal glycine (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:20818167, PubMed:21177865, PubMed:22302004, PubMed:27527864, PubMed:28287329, PubMed:28633005, PubMed:29458288, PubMed:30661429). Exposure of the glycine at the C-terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy (PubMed:15169837, PubMed:15187094, PubMed:17347651, PubMed:19322194, PubMed:21177865, PubMed:22302004). Protease activity is also required to counteract formation of high-molecular weight conjugates of ATG8 proteins (ATG8ylation): acts as a deubiquitinating-like enzyme that removes ATG8 conjugated to other proteins, such as ATG3 (PubMed:31315929, PubMed:33773106). In addition to the protease activity, also mediates delipidation of ATG8 family proteins (PubMed:15187094, PubMed:19322194, PubMed:28633005, PubMed:29458288, PubMed:32686895, PubMed:33909989). Catalyzes delipidation of PE-conjugated forms of ATG8 proteins during macroautophagy (PubMed:15187094, PubMed:19322194, PubMed:29458288, PubMed:32686895, PubMed:33909989). Also involved in non-canonical autophagy, a parallel pathway involving conjugation of ATG8 proteins to single membranes at endolysosomal compartments, by catalyzing delipidation of ATG8 proteins conjugated to phosphatidylserine (PS) (PubMed:33909989). Compared to other members of the family (ATG4A, ATG4C or ATG4C), constitutes the major protein for proteolytic activation of ATG8 proteins, while it displays weaker delipidation activity than other ATG4 paralogs (PubMed:29458288, PubMed:30661429). Involved in phagophore growth during mitophagy independently of its protease activity and of ATG8 proteins: acts by regulating ATG9A trafficking to mitochondria and promoting phagophore-endoplasmic reticulum contacts during the lipid transfer phase of mitophagy (PubMed:33773106)

Isoforms & Post-Translational Modification：Q9Y4P1 has 5 isomers: Q9Y4P1-1: 44294 Da (predicted); Q9Y4P1-2: 52529 Da (predicted); Q9Y4P1-3: 31042 Da (predicted); Q9Y4P1-4: 37037 Da (predicted); Q9Y4P1-6: 42622 Da (predicted).
Phosphorylation at Ser-383 and Ser-392 promotes autophagy by increasing protein delipidation activity without affecting proteolytic activation of ATG8 proteins (PubMed:26378241). Phosphorylation at Ser-316 by ULK1 inhibits autophagy by decreasing both proteolytic activation and delipidation activities (PubMed:28821708). Phosphorylation at Ser-316 is dephosphorylated by protein phosphatase 2A (PP2A) (PubMed:28821708). Phosphorylation at Ser-34 by AKT2 promotes its hydrolase activity, leading to increased proteolytic activation and delipidation of ATG8 family proteins (PubMed:30443548). Phosphorylation at Ser-34 by AKT1 promotes mitochondrial localization and inhibition of the F1F0-ATP synthase activity, leading to elevation of mitochondrial reactive oxygen species (ROS) (PubMed:29165041);Ubiquitinated by RNF5, leading to its degradation by the proteasome;S-nitrosylation at Cys-189 and Cys-292 in response to high glucose decreases both proteolytic activation and delipidation activities;O-glycosylated by OGT, leading to increase protease activity, thereby promoting the proteolytic activation of ATG8 family proteins;Forms reversible intrachain disulfide bonds in response to oxidative stress (PubMed:31880198). Forms interchain disulfide bonds, leading to formation of homooligomers in response to oxidation (PubMed:31880198)
Subunit：Interacts with PFKP; promoting phosphorylation of ATG4B at Ser-34 (PubMed:33607258). Interacts with GBP7 (By similarity)

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
